Application July 30, 1932, Serial No. 626,330 2 Claims. (01. 20 40.5

An object of this invention is to clean the surface of the glass in the car doors and windshield of an automobile.

Another object of this invention is to provide 5 an automatice cleaning attachment which will be simple in construction, simple and positive in operation and which will furthermore, be of a decorative nature so as not to detract from the attractiveness of the vehicle to which it is at- 10 tached.

Advantages incident to the invention are ease and facility in the operation of cleaning attachments, and method of spraying the glass by air pressure. v

15 A further object of the invention is to provide a device of such character which may be easily operated and which will discharge upon the surface of the glass a measured amount of cleaning fluid or other suitable liquid.

20 Changes in the form, proportions and minor details of construction may be made within the scope of the claims without departing from the spirit of the invention.

Other objects, advantages and features of in- 25 vention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

The accompanying drawing illustrates the invention.

30 Figure 1 is a fragmental exaggerated perspective view of the invention as applied to a fragment of an automobile door showing the glass in lowered position.

Fig. 2 is a perspective detail view on a small scale showing one of the wiper frames with the rubber wiper fixed therein.

Fig. 3 is an enlarged fragmental sectional view showing the fluid feed valve, air pump and a fragment of the fluid container tank.

40 Fig. 4 is an enlarged fragmental sectional detail view of the Y connection.

Fig.5 is a fragmental detail view of a sliding door constructed in the door of the car that permits access to the container tank and pump.

45 i designates an automobile door which is of the closed top type and only such portion thereof illustrated as required tolocate the cleaning device of my invention. The glass guide 2 and window sills 3 and 4 of the automobile .door are, or

may be of any approved construction.

The container tank 5 is so constructed and arranged to fit snugly in the bottom of the automobile door as shown in Fig. 1 and is provided with a glass sight 6 so that the amount of fluid 1 55 can be determined at all times in the container.

To fill the container with cleaning fluid a filler cap is provided as at 8 that is easily removed to fill and then replace. A sliding door la is provided, a fragment of which is shown, that slides in slide ways lb to allow access to the glass sight 5 and container tank.

The container tank 5 is provided on its top with a threaded boss 9 projecting upwardly and having a bore l0 therein.

An air pressure housing ll fixed to said thread- 10 ed boss 9 by a connecting nut l2 and interposed between the air pressure housing I l and threaded boss 9 is a metal washer l3 provided with a downwardly extending fluid tube l4 that permits the fluid I to flow upwardly therein when forced by air pressure from the container.

Connecting up with the fluid tube I4 is a vertical bore l5 that passes through the length of the pressure housing ll into a larger chamber IS.

A pressure control housing I! is fixed to and directly above the air pressure housing H by the coupling l8 and at its top is fixed to the feed tube is by the coupling nut 21! and a coil 2| is shown in the tube l9 to take care of vibration.

At the top end of the feed tube I9 is connected a Y connection 22 by the coupling nut 23 and fixed to the Y connection at its forked end are the spray nozzles 24 and 25 by the couplings 26 and 21.

The spray nozzles 24 and 25 are provided with a plurality of holes 28 through which the fluid is sprayed upon the glass window 29.

30 indicates a wiper frame of which there are two constructed and fixed to the window sills 3 and 4 by the screws 3| as shown in Fig. 1 of the drawing.

The wiper frame is provided with holes 32 and a groove 33 into which is fitted the rubber wiper 3 which can be replaced when worn by inserting a new wiper.

There are two rubber wipers required for each car window and fixed on each side of the window glass so that they will always press against the surface of the glass when the window is being raised or lowered.

An air pressure pump is shown as at 35 and comprises a housing 36 and a cap 31 with a plunger 38 extending therethrough having a knob 39 so that the operator may grasp it to force air' into the check valve 40 through the orifice 4| on into the channel 42 into the container tank 5.

The check valve housing 43 is screwed into the air pressure housing II at an angle as shown at 44 and the check valve comprises a valve ball 45 held in place by the valve spring 46 to prevent any air from escaping from the container tank 5.

In the fluid control housing I! is provided a pressure release valve 41 which releases fluid to the wiper to be sprayed through the spray nozzles 24 and 25.

Said fluid is fed through from the chamber I6 to a vertical bore 48 to the pressure control chamber 49 into the orifice 50 which connects directly to the feed tube l9.

To operate the fluid release valve 41 the thumb knob 5| is pushed inward which allows the fluid to flow into the orifice 50 from the bore 48, then the valve is released and the spring 52 will close the valve automatically.

I claim:

1. A device of the character set forth for cleaning window glass in an automobile comprising a container tank in the door; a pressure housing connected at the top of said container tank having a force pressure pump and a fluid feed pipe connected to and extending upwardly from said pressure housing; a connection being mounted at the top of said fluid feed pipe having a fluid spray on each side of the glass so that the glass is cleaned when raised and lowered.

2. A device of the character set forth for cleaning window glass in an automobile comprising a container tank in the door; a pressure housing connected at the top of said container tank and a fluid feed pipe connected to and extending upwardly from said pressure housing; a connection being mounted at the top of said fluid feed pipe having a fluid spray extending on each side of the window glass to clean the glass when it is raised and lowered; said pressure housing having a check valve that regulates the flow of fluid to said spray and a force pressure pump that forces air into said container tank.
